PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 676,241, dated June 11, 1901.

Application 516a July 25, 1900.

To all whom, it may concern:

Be it known that 1, JOHN F. MoNUTr, of Warren, in the county of Trumbulland State of Ohio, have invented certain new and useful Improvements inPrinting-Presses; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothersskilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements inprinting-presses, having reference primarily to that class of pressesemploying one main cylinder and a series of cylinders arranged incircular relation to and designed to coact with the main cylinder, as inmulticolor-printing.

The primary object of the invention is to effect a relative adjustmentbetween the main cylinder and the series of surrounding cylinders, tothe end that they may be instantly thrown into or out of position forconjoint operation. V

Afurther objectis to automatically and successively effect the throw-offof the several cylinders upon an interruption in or a cessation of thefeed-supply; and a further object is to provide an improved trippingdevice for actuating the throw-01f mechanism in the event ofanyirregnlarity or interruption in the feedsupply.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective, withparts broken away and others omitted, looking inwardly from the rear atone side of thepress-l'rame, the tripping device being shown andportions of the several cylinders indicated in dotted lines. Fig. 2 isan end elevation with parts broken away and other parts omitted. Fig. 3is a sectional view on line33, Fig. 2. Fig. lshows the main orimpression cylinder with its encircling casing removed.

rolls in front elevation. Fig. 11 is a view looking at Fig. 10 on line11 11.

Referring to the drawings, 1 designates the frame of a printing-press.

2 is the main or impression cylinder, sui;t ably journaled in the sidesof frame 1 and operated by mechanism not shown. Outside of and partiallysurrounding the cylinder 2 is a series of circularly-arranged cylinders4. These latter, which are smaller in diameter thantheimpression-cylinder, are designed to carry the type forms or plates, andeach cylinder is provided with a separate set of inking-rolls 5, as isrequired in multicolor-printing. These surrounding cylinders arejournaled at their ends in boxes 7, each of which is movable in parallelgnideways 8 in the sides of frame 1, thereby permitting of thelongitudinal adjustment of each of the type-carrying cylinders and inconsequence the adjustment of the several cylinders of the seriesrelatively to the main or impression cylinder.

Each box 7 is connected by a link 9 to an ad jacent cam-shaft 10,journaled in the sides of the frame, such links being located in endextensions of the housings of the severalboxes and formed with an eye ineach end to accommodate, respectively, the cam-shaft l0 and a pin 12, bywhich it is loosely held to the inner end of its respective box. Thepartial turning of the several cam shafts will throw each of thetype-carrying cylinders into or out of working position in relation tothe impression-cylinder. Coil-springs 13 act on each box to insureevenness of movement and prevent jarring. On the inner end of eachcam-shaft is a tumbler 14:, formed with curved ends. Adjacent to eachtumbler is a stop 15 to limit its movements to a partial rotation.

The impression-cylinder 2 carries mechanism for actuating the severaltumblers, so as to throw in or out the several type-carrying cylinders.Such mechanism is shown as embracing longitudinally-movable bolts 16 and17, projecting through the ends of the cylinder into the path of thecurved ends of the several tumblers, the engagement of such bolts withthe tumblers being controlled according as it is desired to throw off orthrow in the several type-carrying cylinders, one bolt being withdrawnwhen the other is projected so as to engage the tumblers. The

tumbler-actuating mechanism is diiplieated at diametrically oppositesides of theimpression-cylinder for the reason that two sacks areusually printed in each revolution of the cylinder.

ends within the cylinder are formed with slots 18 in box-like portions19, in which slots of the two sets of bolts fit the ends of levers 20and 21, fulcrumed on posts 22; projected from inder. To the lever isseeured a springpressed rod 24 for holding the parts fii'cedin thepositions into which they are positively moved. Looking at Fig. 4, thetwo sets of actuating mechanism are operated from the left-hand endthatis, movements at this end are communicated to the bolts at the "otheroi' rig'ht-hand end of the cylinder. I At thi'soperating end, on a linebetween but to f sideof the bolts 16 and 17, is a suppleas bolt 25. Thisbelt at its inner endis tl7-at the ether end ofthe cylinder, whiletd'tfhe e'oafcting bolt 16 at this end is connect ed a rod'27, whichleads from the bolt 17 at 'the'epeiating end. \Vhen bolt 17 at the leftt tirced ihward, the corresponding bolt 17 bolt 16fate'a'ch end isprojected'o ut'- 3 "ents of the bolts 17 and 25 at th'e'ophd 17 at theother end through-the conii e feriner controllingth'e movement also of"twbtous 17 at the opposite ends are i'ro'ss the frame in front of theimpressioniider'and is provided with a liandle32, by eh it'is turned toset the switch for throwl switehisfermed with two cam-surfaces 33 withwhich will engage'the inner bolt or the supplemental bolt 25,ace'ordi'ng as switch is positioned to throw the typices ti 1efthrow=inthe switchoccu pies its lower the im s'ion-cylinder while for effeetingthe thr'ew off the switch is raised toward the periphery of thecylinder. These movements of the switch are limited by stops 35.

th'atis; toward thea xial center of 36 is the feed mechanism andtripping device. It comprises two upper feed-rolls 37, having segmentalcontact peripheries. These rolls are on a sleeve 38, fast onashaft 39,mounted at its ends in the sides of the press frame and driven from oneend by suitable mechanism. Between two ears 40 of sleeve 38 is pivoted atrip-arm 41, which projects forward of the contact portion of thefeedrolls 37, and by engaging with a stop 42 said arm will in therevolution'of the rolls intersect the line of travel of the. stock tothe press. The lower feed-rolls 43 are fast on a shaft 44, which issupported by two links 45, loosely hung on a cross-pin 45,'projectedlaterally from a ost 46of a casting 47. Two coil-springs 48serve to libldjtheflow'er reedrolls in proper position ielative te theupper feed-rolls and allow for'any I ality inthe thickness of the steck,the

ps 48. The shaft 44 is'formed in sections '0 nnected together byflexible joints and is area by the shaft 39 of theupperfeed 11s, sa Ihaving intermes'hin ear-sh 1s att re end.

The casting 47 is fast on a tie-rod 49, held at its ends to theside's ofthe press-theme.

The engagement or the iev eteo with the dog 52 is insuredby a's rin'g'se'n earin downwardly on its forwardly-projected arm. Theupright arm of this "firip-'-;1everexteiids to the'line of passage ef.the sjt'oek, as'to be engaged by the meat-m 41 if the latter be'notraised siifideieiit to clear the'endof'tli'eleier, as when the steel; isnetin "p6. chat the proper time between the ripper ah'd lbwerfeed-rolls. I hen this-ec'ehrs;the'tiip-ariii 41 will en gage trip-lever50, turning the-latter I on irs ruicmm and n-itgtnedeg 52, whereupon thesprite-neutered red 31 willthrow the switch outward into the path oftravel of the then'extenciea bolts 25, which iipoiicoming in Contactt-lierewith 'will be forced inwardly, resulting in the withdrawal ot thebolts ldan'd the fereingeiitot bolts 17. The latter willft'he'n acteonseeuti'vely entli'e' several summers aiideifectft ie steward 'ni'ove-I ment ofthe b iieseftnetype-cy1i1iders.

In" practice the op'ei ittor first sets "red 31 as against the tension QE i'ts'fsprihg, placing dog 52 in engagement with the trip-lever. Theswitch being thus th ho'wn inward, "the bolts 17 will be 'foreed i'nithecylinder, while the bolts 16 and '25 will be pi'ojected'eiitward, andupon the former coiniiig in'eon'taet with the tumblers'of the type'cyliilders will act thereon to throw the latter i'nt o worl'zing"position relatiyely to the i'm' i-sss tmcyl n er, The stock is broughtup toth'e feed-rells by any suitable means, and at the proper time suchrolls, which are intermittently operated, will take up one article andfeed it forward to tive to the impression-cylinder, and means theimpression-cylinder. As the article travels forward the trip-arm comesin contact therewith and is thereby turned on its pivot sufficiently farto clear the trip-lever. The parts will continue to retain the positionstated as long as the proper feed to the press is maintained; but uponany interruption therein or failure to properly position the stockbetween the feed-rolls the trip-arm will engage the trip-lever,releasing the switchshaft, which will throw its switch into its upperposition in the path of travel of the supplemental bolts 25. These beingforced in- Ward, the bolts 16 will be withdrawn and the bolts 17 forcedout, so that they will contact with the several tumblers and eifect thesuccessive throw-0E of the type-carrying cylinders.

By the means described upon failure in the feed-supply thetype-cylinders are successively thrown off; but stock passing throughthe press when such failure occurs will be fully printed before thethrow-off of all the type cylinders is accomplished. Likewise when theaction is reversed the successive throw-in of the several type-cylindersis timed to occur with the presence of stock to receive the severalimprintsthat is, the actuating mechanism occupies such relation to theposition of the stock on the impression-cylinder that each of thetype-cylinders is thrown into position in time to coact with theimpressioncylinder. In this way no impression will be madenpon thetympan-sheet, the throw-off or throw-in of each cylinder occurringaccording as stock is absent or present.
